Guide To P07A8 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P07A8 can be explained as Transmission Friction Element "D" Performance/Stuck Off.

If there are some issues with the internal friction materials in the automatic transmission, it will then lead to unpredictable driving conditions as far as shift timing, torque output and many other complications. Internal slippage can be caused due to uncommon paired tires, insufficient inflated tires.

Do you want to know more about the P07A8 fault code? Don’t worry! Parts Avatar Canada is here at your service.

The letter “D” in this case might refer to some possible differences. The person might be dealing with a particular circuit/wire or there can be a certain friction element within the transmission. That is the reason why it is very important to have a look at your service manual for particular locations, distinctions, and other such specifications. When the engine control module would detect a struck off in the internal "D" friction element inside the transmission, then P07A8 code would start appearing.

What causes this problem with the Transmission Friction Element "D" Performance/Stuck Off?

• Tattered friction element
• Malfunctioning engine control module
• ATF might be dirty
• Bumpy tire sizes
• ATF might be low
• The rotational speed/circumference may be unequal Defective transmission control module
• There can be some issues related to the wiring
• There can be water damage to module and harness

1. Electronic Control Unit - A faulty Electronic Control Unit can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Automatic Transmission Fluid - If everything is alright with PCM, then there is surely some defect in Automatic Transmission Fluid. Get it replaced before the situation gets worse.
3. Powertrain Control Module - P07A8 code can display due to some faults in the Powertrain Control Module. So it is very important to replace the Powertrain Control Module with us at equitable prices.
4. Auto Transmission Control Module - Do you remember when was the last time you got your Auto Transmission Control Module checked up? A defective Auto Transmission Control Module can cause a lot of issues like displaying P07A8 code.
5. Automatic Transmission Filter - Poor Automatic Transmission Filter can cause a lot of difficulties, so why not get it replaced at time?
6. Body Control Module Component - Are there some faults in your Body Control Module Component? Don’t waste time and get them replaced or else P07A8 code can turn up.
7. Engine Control Module - Everything is fine with Auto Transmission Control Module and still P07A8 code triggering? Then you must get your Engine Control Module checked.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P07A8 code to be stored:

A good starting point is always a technical service bulletin search for your particular vehicle. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle.

Here is the Step 1

It is very important to follow the basic maintenance procedures accordingly at this point, as far as the transmission's health goes, start at the fluid. Your ATF (Automatic Transmission fluid) should be fully clean, free of debris and also, proper maintenance schedules have to be followed to avoid more defects. If you don’t remember the last transmission has been serviced (i.e. filter+fluid+gasket), it’s a good idea to perform this before continuing. There might be a bit of debris in your oil that is trapped internally. It may only take a simple service, so make sure you are aware of the last A/T service

Here is the Step 2

You must find a junction connector when you are attempting to find the connector/harness for this system. There may be one "master" connector so make sure you are working with the right one by referring to your manual. Make sure that the connector itself is seated properly to guard a fine electrical connection. Now when the connector is situated on the A/T, it may be subject to vibrations due to which the connections might become loose or physically damage them. Not to mention, the possibility of ATF to saturate connectors and wires causing future or present issues.

Here is the Step 3

All of us should be fully aware of the overall condition of your vehicle. Rough tires, worn out suspension parts, inaccurate wheels, all of these can and will cause issues in this system and possibly others as well, so even things out, and you may rid of this code.

Common Mistakes When Diagnosing The P07A8 Code

• Internal transmission might start failing
• Non-observance of the transmission valve body solenoid
• Diminishing transmission fluid level
